The motivation of this survey. Several existing survey papers [1]}, [2]}, [3]}, [4]}, [5]} have provided a detailed introduction and analysis of the IM problem. However, some critical emerging trends of IM research haven't been thoroughly discussed in these surveys, i.e., IM query with location information. This has motivated us to comprehensively summarize the research progress of location-driven IM through a fine-grained classification and a systematic analysis of existing location-driven IM methods.
